BTEX is a grouping of structurally similar volatile organic compounds including benzene, toluene, ethyl benzene and the three xylene isomers. These compounds are known pollutants and are typically found near petroleum production and storage sites. BTEX are regulated toxic compounds while benzene is also an EPA target carcinogen. The investigation of these compounds, especially in drinking water at low levels, is critical to protect public health. This application note focuses on exceeding the current EPA detection limit requirement for BTEX while meeting and/or exceeding all other criteria in EPA method 524.2 for these analytes.
